摘 要:为明确威宁烤烟种植地区最佳的地膜使用方法,研究了不覆膜、35 d揭膜和全生育期覆膜对烤烟产量和品质的影响。结果表明,35 d揭膜和全生育期覆膜均能促进烟株早生快发,提高烟叶产量和产值,以全生育期盖膜处理效果最好,烟叶产量和产值分别较不盖膜处理提高20.9%和48.6%;但35d揭膜处理和全生育期覆膜处理均导致烟碱含量升高、钾含量降低,对烟叶品质不利。Effect of non mulching,mulching for 35 days,and mulching for whole growing period on yield and quality of flue-cured tobacco was studied to find out the optimal mulching method of plastic mulching film in Weining tobacco growing areas.The results showed that both the treatments of mulching for 35 days and mulching for whole growing period,promoted the germination and growth,and improved the yield and output value,especially mulching for whole growing period was optimal,yield and output value increased 20.9% and 48.6% compared with non mulching;However,mulching for 35 days and mulching in whole growing period resulted to higher nicotine content and lower potassium content,both treatments negatively affected the quality of flue-cured tobacco.
